Proton microprobe analysis was used to determine the fluoride concentrations in enamel and dentin surfaces exposed to a fluoride-containing and a conventional amalgam in vitro. After seven weeks of exposure, a considerable fluoride uptake was demonstrated from the fluoride-containing amalgam. The fluoride deposition was greater in the dentin than in the enamel. The greatest fluoride concentrations in enamel surfaces, about 4000 ppm, were found in the outer 0.05 micrometers of the tissue. In the dentin the greatest concentrations, about 9000 ppm, were found at a depth of 11.5 micrometers. This study demonstrates the ability of the fluoride-containing amalgam to deposit fluoride into dental hard tissues.
使用质子微探针分析来测定在体外暴露于含氟汞合金和传统汞合金的牙釉质和牙本质表面的氟浓度。暴露七周后，证明从含氟汞合金中有大量的氟摄取。牙本质中的氟沉积比牙釉质中的更多。在组织外层0.05微米处发现牙釉质表面的最大氟浓度约为4000 ppm。在牙本质中，最大浓度约为9000 ppm，出现在11.5微米的深度处。这项研究证明了含氟汞合金将氟沉积到牙齿硬组织中的能力。
